2020 GMC ACADIA Vehicle Speed Control Problems

The vehicle was purchased brand new from Serra GMC in Washington Michigan in April 2020. It has been back to the dealer 5 times for the same issue, with another 4 times that it was not taken into dealer! Reoccurring issue involves the instrument cluster, All gages and visual indicators go to zero (speed, tach, fuel, temp, etc...) as well as getting a notification that the traction control is disabled, the ABS is disabled, cruise is disabled, and other electronic aid. This happens at highway speeds and to loose all function is a safety concern, it is not repeatable and happens randomly but it is the same issue. The dealer claims to fix the issue but it always comes back. GM has told me to accept the issue as its not detectable however this is unacceptable as it puts my family at risk. I have videos of the instrument cluster...

The ACADIA 2020 while in slow motion approaching my private condominium parking spot, accelerated autonomously and then slammed into the cement wall. Airbags deployed, no warning of collision, seriously damaged both car and cement wall. No bodily injuries. I researched the possible cause coded P2138 which involves the drive by wire sensors which connect the throttle pedal and the CPU that controls the mechanical throttle gas system. That might be the cause of the autonomous acceleration like explained about the P2138 sensors issues.

WHILE IN MOTION- BLIND SPOT SENSORS TURN ON WHEN THEY SHOULD NOT AND VICE VERSA. TRACTION CONTROL HAS FAILED MULTIPLE TIMES WHILE DRIVING. PREDICTIVE BRAKING HAS ACTIVATED IMPROPERLY MULTIPLE TIMES WHILE DRIVING. CAMERAS WENT OUT AND THEN BATTERY COMPLETELY DIED. WAS TOLD FIXING BATTERY WOULD FIX VEHICLE. THIS HAS PROVEN TO BE UNTRUE. VEHICLE IS CURRENTLY IN FOR SERVICE FOR THIRD TIME. REMAINS UNDER WARRANTY, AS I HAVE HAD IT THREE MONTHS. MOST RECENT DATE HAS BEEN USED BUT I'VE HAD PROBLEMS SINCE LITERALLY THE FIRST FULL DAY I HAVE HAD IT.
